Use method of attapulgite non-woven saline-alkali soil greening tree planting bag two-component nourishing cream

Abstract

The invention discloses a method for using a two-component nutrient cream of an attapulgite non-woven saline-alkali land greening tree-planting bag. After soaking, take it out and dry it, the nutrient paste of component A is firmly adsorbed and adhered to the outer layer of the nutrient film of component B; add the attapulgite soil conditioner for saline-alkali land greening and tree planting into the tree planting bag, and the nutrient paste to be transplanted in the tree planting bag The saline-alkali seedlings enter the normal growth and development stage, together with the tree-planting bag, they are directly cultivated in the saline-alkali soil; the nutrient paste of components A and B adsorbed and adhered inside and outside the tree-planting bag will continuously neutralize the soluble salts in the saline-alkali soil outside the tree-planting bag, Reduce the pH value of the saline-alkali soil around the outside of the tree-planting bag, greatly enhancing the saline-alkali resistance of the saline-alkali-resistant seedlings inside the green tree-planting bag. cloth saline land greening tree planting bags.

Description

technical field [0001] The invention relates to a tree-planting bag, in particular to a method for using an attapulgite non-woven fabric saline-alkali land greening tree-planting bag two-component nutritional cream. Background technique [0002] Saline-alkali land means that the salt contained in the soil affects the normal growth of crops. Plants in severe saline-alkali soil areas can hardly survive. Soluble salts reduce the ability of plants to absorb water and nutrients, relatively reduce the content of soil organic matter, seriously lack nitrogen, phosphorus, potassium and trace elements, seriously damage the soil aggregate structure, reduce air permeability, and reduce the activity of aerobic microorganisms , slow soil maturation, resulting in soil compaction. Due to salinization, the physical and chemical properties of the soil deteriorate, and the living conditions of plants deteriorate. The work of greening and tree planting in saline-alkali soil is very difficult, ...

Problems solved by technology

[0004] The disadvantages of the above-mentioned patents are: the "rain-gathering, water-saving, fertilizer-preserving, tree-planting bag" is "during natural rainfall, the net formed by the root system will store rainwater, provide guarantee for the survival of trees, realize the survival of saplings, and improve the ecological environment." In nature, deserts or saline-alkali lands are geographically located, and the natural rainfall is less, so the rain-gathering, water-saving, fertilizer-preserving and tree-planting bags are not suitable for afforestation in deserts and saline-alkali lands.

[0006] The disadvantages of the above-mentioned patents are: (1) the bag body includes an inner liner and an outer layer, and the production cost is relatively high, which is unfavorable for popularization

(2) The waterproof layer is made of powder waterproof material, the powder waterproof material is bentonite or modified bentonite or natural rock powder or anti-seepage sand or organic silicon waterproof powder, these powder waterproof materials are difficult to adhere to the surface of the tree planting bag , although "the fixed structure of the waterproof layer is provided between the inner lining layer and the outer layer", in order to "the waterproof layer can also be breathable while being waterproof", the powder waterproof material in the tree planting bag cannot be adhered to the The surface of the tree-planting bag is not waterproof. When the tree-planting bag is in contact with the soil or the air, the water contained in the tree-planting bag is connected with the outside world and will be quickly distributed to the saline-alkali soil or soil outside the tree-planting bag. In the air, the soluble salts in the saline-alkali land can easily penetrate into the tree-planting bag, causing the seedlings in the tree-planting bag to fail to grow and develop normally, and even cause the seedlings in the tree-planting bag to die. The role of moisture conservation, not suitable for afforestation in saline-alkali land

[0007] According to the survey, in the saline-alkali land for greening and tree planting, the survival rate of seedlings within three years is less than 70%.
